Title: Method and apparatus for generating anti-aliased vectors, arcs and circles on a video display
IPC: G06T11/20
Filed: 1987-04-06
Abstract: A method and apparatus for anti-aliasing vectors, arcs and circles comprising a plurality of pixels on a video display. The distance, d, of each pixel from the centerline of a curve is computed using a plurality of linearly dependent equations. The intensity of each pixel is set as a function of the magnitude of the distance, d, of the pixel from the centerline of the curve. In some cases, the distance, d, is compared with ranges of distances and the intensity of the pixel set according to the range within which the pixel is located. In other cases, the intensity of the pixel is simply inversely proportional to its distance, d, from the center-line.

Title: Plant anaerobic regulatory element
IPC: C12N5/10
Filed: 1988-02-02
Abstract: DNA sequence elements which affect anaerobic induction of genes in plants are identified and characterized. These sequence elements, designated anaerobic regulatory elements, confer inducibility by anaerobic condition on downstream plant-expressible promoters and their associated structural genes. In particular, those sequences associated with anaerobic induction of the maize alcohol dehydrogenase and aldolase genes have been identified. These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to product chimeric, anaerobically inducible genes. Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

Title: Improvements in and relating to the manufacture of wire binding elements
IPC: B42B5/10
Filed: 1988-05-18
Abstract: A machine for transforming zigzag wire to the slotted tubular form ready for use as a binding element comprises means for feeding a strip of zigzag wire longtitudinally, means for arresting the feed of each prong of the wire strip as it reaches a shaping station, means for clamping each prong at that station and means at the station for shaping each clamped prong. The shaping means comprises two or more forming tools mounted on rollers which are driven by drive shafts, at least one roller being angularly adjustable relative to its drive shaft. This allows the operation of the forming tools to be synchronised so that symmetrical shaping of the zigzag wire is achieved. The feed means are rotary and means are provided whereby the feed of each prong is arrested for at least one eighth of each revolution of the rotary feed means The shaping of the zigzag strip is facilitated and improved since the strip is held stationary for a relatively long period of time.
Patent EP-0301756-A3 (EP)
IPC: H01L21/027
Filed: 1988-07-20
Abstract: A stripping composition for removing positive organic 
photoresist from a substrate, such as a semiconductor 
wafer, contains a triamine, such as diethylene triamine, 
and a nonpolar or polar organic solvent, such as N-methyl 
pyrrolidone. This composition will remove positive 
photoresist from semiconductor wafers, even after ion 
implantation into the wafers through the positive photo­
resist. The wafers are immersed in the composition, for 
example, at a temperature of 110°C for five minutes, in an 
ultrasonic bath after heavy ion implantation doses through 
the photoresist, such as 1 x 10¹⁶ ions/cm², for complete 
removal of the photoresist. Prebaking the photoresist at 
a temperature of between about 150 and 220°C. for a time 
of from about 15 minutes to about 30 minutes, prior to 
stripping the positive organic photoresist layer with the 
triamine, enhances the removal.

said clamp (5) being provided therefor with a pair of resilient 
side branches to effect the gripping action, which branches 
derive from a further midlle branch or bracket, acting as a means 
for holding the body of the umbrella support.

Title: Method and apparatus for testing with magnetic powder
IPC: G01N27/84
Filed: 1989-01-24
Abstract: A method and apparatus are specified for testing ferromagnetic materials with magnetic powder, in which the workpiece is introduced into an elongated air coil (1 - 4) with ends bent at right angles. The full magnetic field flows through the workpiece (21). The defects in the workpiece are preferably detected at its top while the magnetic powder (20) is picked up at the bottom and the workpiece is rotated through at least 180 DEG  for observation. The apparatus makes it possible for a workpiece to continuously pass through it, with a continuous observation of the surface of the workpiece being possible at the same time as it is rotated and it being possible to detect transverse and longitudinal defects simultaneously or consecutively. The magnetic flux through the workpiece is produced without touch and without contact. The invention makes possible simple, precise and rapid surface defect testing of ferromagnetic materials without making contact to the workpiece or adjusting the testing apparatus. <IMAGE>

Title: Method and apparatus for frequency control of multiple oscillators using a single frequency-locked-loop
IPC: H04N7/167
Filed: 1989-10-07
Abstract: Frequency control of multiple oscillators using 
a single frequency locked loop is accomplished by 
a single frequency-control device that is time-­
shared with a plurality of voltage-controlled 
oscillators and selectively establishes a "desired" 
frequency for each oscillator. The output of each 
oscillator is, in turn, selectively routed to a 
frequency counter which measures the "actual" 
frequency of the oscillator. A comparison between 
the desired frequency and the actual measured 
frequency for each oscillator is made, and an error 
voltage developed. This error voltage is routed to 
the appropriate capacitor, which stores the voltage 
required to keep the selected oscillator on 
frequency until the next time it is measured.

Patent EP-0338748-A3 (EP)
IPC: G04C9/00
Filed: 1989-04-17
Abstract: An electronic timepiece comprises an oscillator 
circuit (1) for generating an oscillating signal having 
a predetermined frequency, and a frequency divider 
circuit (2) responsive to the oscillating signal for 
supplying an output for intermittently driving a movable 
actuator (6). Storage means (7) are provided for 
storing kinetic energy of the actuator, together with 
means (10) for controlling release of the stored energy 
for smoothly driving a time keeping hand (9). Setting 
means (11) stop the time keeping hand during correction 
of the time displayed by the timepiece. The frequency 
divider circuit is arranged such that at least a portion 
thereof is held during time correction in the state 
prevailing immediately prior to time correction. This 
may be achieved by employing state holding means (3; 77; 
75) for holding the at least a portion of the frequency 
divider circuit in said state during time correction. 
Alternatively, the frequency divider circuit may be 
arranged such that the at least a portion thereof is set 
in said state during time correction.
Patent EP-0343838-A3 (EP)
IPC: H03K3/356
Filed: 1989-05-17
Abstract: A high speed CMOS binary up/down counter (10) having 
a 200 MHZ clock rate comprises a 4-bit counting section 
that may be concatenated in multiple 4-bit sections. 
The counter (10) performs in an up-count mode or a down-­
count mode in accordance with the state of an up/down 
mode select signal (U/D). Each stage (11) of the 4-­
bit counting section comprises a propagate/kill/generate 
gate (28) for determining the status of a carry signal 
(CO) to a next stage, except the last stage of a 4-bit 
section, which does not require such a gate because it 
is coupled to a carry-forward generator (34) along with 
the outputs (A₀,A₁,A₂,A₃) from the other preceding 
stages in the section. Each 4-bit section (10) 
performs the counting function through a successive 
process of a modulo-two sums formed by modulo-2 summers 
(20,22,24,26) of a lower order carry and the current 
state of a counter stage without the need for 
cumbersome gating structures. The count of each 
stage is stored in a D-type flip-flop (12,14,16,18). 
The Q or  Q  output of the flip-flop is selected by a 
selector (40,42,44,46) to provide the current state 
of the stage to the summer (20,22,24,26) in dependence 
upon the mode select signal (U/D).

prevention of increasing the number of components and the 
increase of cost as a result of increased assembly steps 
and/or the required man-hours.
